摘要:

本文研究了利用Misner-Sharp-Hernandez质量作为内能对Schwarzschild-de Sitter黑洞进行减维相空间量化。在引入减维相空间的规范变量后,我们推导出黑洞事件视界及MSH质量的离散谱。利用MSH质量谱获得黑洞熵。黑洞及宇宙视界熵显示出对Bekenstein-Hawking项的对数修正。我们的结果支持了SdS热力学中对数形式的量子修正的稳健性。

英文摘要:

This paper investigates the quantization of the Schwarzschild--de Sitter (SdS) black hole (BH) using the Misner--Sharp--Hernandez (MSH) mass as the internal energy in a reduced phase space framework. After introducing the canonical variables of the reduced phase space, we derive a discrete spectrum for the surface areas of the BH event horizon (EH) as well as MSH masses. We utilized the MSH mass spectrum to obtain the entropy of the BH. The entropy of the BH and cosmic EHs reveals a logarithmic correction to the Bekenstein--Hawking term. Our results support the robustness of the logarithmic form of quantum corrections in SdS thermodynamics.
